Item Forecasting approach for Blind Spot Collision Alert(ACM Digital Library, 2021-03-22) Djamel BEKTACHE, Yakoubi Mohamed Amine and Ghoualmi NaceraEvery year many accidents involving all categories of road users. However, some accidents are related to the blind spot, due to the deficiency of visibility in this zone, also lack of information or negligence. In this work, we focused on the road safety applications. The main of our researches is to alert the risk of blind spot collision. For this we designed a new approach, namely FBSCA, Forecasting Blind Spot Collision Alert, the driver alerts his neighbors for a possible accident related to the blind spot. The most interesting scenario testing includes the case where the vehicles need to exchange information in real-time in order to avoid traffic collisions when their visibility is hindered by road obstacles. For the implementation and testing of our approach we used popular network simulation tools such MOVE, SUMO and Ns2, we provided an assessment of proposed solution in order to alert the blind spot collisions for all neighboring vehicles.Item An Optimized Path Planning for Wheeled Robot in Obstacle Environments(IEEE explore, 2021-11-03) Mohamed Amine Yakoubi; Djamel Bektache; Abderahmane Gaham; Raouf ToumiIn this paper, we have proposed an obstacle avoidance algorithm for a path planning in unknown environment for a mobile robot based on the fuzzy logic control. Therefore, the wheeled mobile robot is equipped with 3 wheels, one steering wheel and two fixed wheels and mounted on the same axis. Its task is to move from a starting position to a target position. For this, our proposed algorithm creates one or more imaginary target and applies a fuzzy logic control system, which is adopted by a rule table that is induced from two inputs data (the distance and the angle between the robot and the target) and two outputs data (the angle orientation and velocity of the steer wheel). Experimental results show the effectiveness of the proposed algorithm.Item Reconfigurable Wireless Sensor Networks Simulator (RWSNSim): A New Discrete-event Simulator(SCITEPRESS, 2022-07) Hanene Rouainia; Hanen Grichi; Laid Kahloul; Mohamed KhalguiReconfigurable wireless sensor networks become an important area in research and industrial communities. With their development and spread, many problems and solutions have emerged. Network simulators have become an essential necessity to study the impact of these solutions on networks in order to avoid huge costs in terms of money, time, and effort if applied on the ground. In this paper, we propose a new discrete-event simulator for WSNs and RWSNs called RWSNSim. We present its description, modeling, and provided services. Finally, to demonstrate the efficiency of RWSNSim, we simulate a case study and detail the simulator functioning steps.Item New Energy Efficient and Fault Tolerant Methodology based on a Multi-agent Architecture in Reconfigurable Wireless Sensor Networks(SCITEPRESS, 2022-01) Hanene Rouainia; Hanen Grichi; Laid Kahloul; Mohamed KhalguiReconfigurable wireless sensor networks became more complex and dynamic systems. Their importance increases with time and more challenges appear. The most important challenges in RWSNs are the energy and software/hardware failure problems. In this paper, we propose a new methodology composed of a set of solutions summarized in the application of the mobility, resizing, and mobile sink nodes using a multi-agent architecture and an energy efficient routing protocol. It contains also a test packet technique to detect the malfunctioning entities and isolate them. Moreover, we develop a simulator named RWSNSim which allows simulating WSNs and RWSNs with and without application of the proposed methodology. It permits also to compare the different results using line charts. Finally, we simulate a case study with RWSNSim in a 3D environment to evaluate the performance of the proposed methodology.Item 3D Mobility, Resizing and Mobile Sink Nodes in Reconfigurable Wireless Sensor Networks based on Multi-agent Architecture under Energy Harvesting Constraints(SCITEPRESS, 2020-01) Hanene Rouainia; Hanen Grichi; Laid Kahloul; Mohamed KhalguiThis paper deals with reconfigurable wireless sensor networks (RWSNs) to be composed of a set of sensor nodes, which monitor the physical and chemical conditions of the environment. RWSNs adapt dynamically their behaviors to their environment. The main challenge in RWSN is to keep the network alive as long as possible. We apply a set of solutions for energy problems by using 3D mobility, resizing and mobile sink nodes. These solutions are based on a multi-agent architecture employing a wireless communication protocol. Moreover, we develop an application named RWSNSim that allows us to simulate an RWSN and apply the proposed solutions. The performance of the proposed approach is demonstrated through a case study. The case study consists of surveying of fire in a forest which is simulated with RWSNSim application.Item Using Deep Learning for Positive Reviews Prediction in Explainable Recommendation Systems(2022-10-26) Hafed ZARZOUR, Mohammad Alsmirat and Yaser Jararweh
